The BMS versus Vishnu N54 tuner fight is one of those never ending wars with battles fought again and again with victories on both sides often leaving fanboys crying and disoriented. It is great to see actual comparisons in the real world instead of the typical forum flame war and we have such a comparison right here. The E90 in the video has a JB4 on map 3 16 psi, BMS meth kit, ER charge pipe, Synapse BOV, AR catless downpipes, HPF intercooler, and BMS DCI. The E92 has the Procede aggressive map at 18 psi, PWM meth kit, AR Downpipes, Vishnu charge pipe, muffler delete, and Stett CAI.

The E90 with the JB4 and less boost surprisingly pulls the E92 with the Procede on both runs. No word on if Shiv@Vishnu had a heart attack after seeing the result or if the Vishnu fanboys grabbed pitchforks and torches and are marching on the location of the BimmerBoost server as you read this. To be fair, the E92 6 speed had clutch slipping and meth issues. Definitely a cool comparison to see and there is no denying the automatic is more consistent. We look forward to seeing a rematch.

Let's compare a new F10 M5 and CLS 63, but remove a spark plug out of the Benz. This will be a good representation of both....

Oh, so you mean intentionally skew a comparison versus what happened here in the real world? It's a fun comparison, not the be all end all. Nobody is denying there were issues but no car was intentionally hampered to portray the JB4 as superior.

I guess because ign correction was set to 0. But he most definitely hit 18.6psi, he will even tell you that.

18.6 psi down low with a lot of cps offset is perfectly within the turbo's efficiency range. Running 18.6 psi past 6500 RPM, that's cause for concern. 18.6 psi with ignition correction set at 0 is asking for trouble unfortunately.

The PWM kit was extremely nice. It came with a few more parts than the BMS kit and took a tad longer to install. It came out looking excellent. I would not spend the extra money on it. But they are both great kits.

sure, its just that one works and the other one not so much just kidding

Mine is as simple as it comes But yes I've always said the PWM meth kit controlled by the Procede is a joke, and still stand by that opinion!

Do you honestly want a tune that can't even update itself properly without erroring out on your laptop with no verification process controlling your methanol injection too? lol.

I ordered in a bunch of nice basic boost switches (the DO ones). So we'll be offering a WW kit variant with just the basic boost switch for those of you using flash tunes but want a simple easy to install/remove meth kit. Price will be $369 and you can pick a CM5, CM7, or CM10 nozzle.

This all just makes me laugh.But yes, the meth kit is working flawlessly now on stg 3 aggressive maps. The culprit was a bad ground, I changed the mount location so I had to find a new place to ground which did not work. I extended my ground wire to work on the original location and it works great now. The clutch is holding, but just barely, hopefully it will hold until tomorrow night and we can make a new video.

not really. if you believe the logic that even 8psi has knock on stock tune with 95+ octane, then surely there isnt enough cps in the world to not damage the motor at 18.6 psi on 93 or less octane
